Hi
I seem to have the same problems as everyone else with the game crashing. At first i was able to run the game for 5 to 10 minutes until it crashed but now it crashes at the loading screen. I have installed the latest Nvidia display drivers, Nforce drivers, the latest Athlon 64 drivers and latest version of Direct X.

On the latest occasion it crashed Windows displayed an application error stating that the instruction at "0x24007107" referenced memory at "0x01033d60" the memory could not be "read".

Forgot to mention that when the game does crash my mouse still works, on occasions i have been able to ctr, alt delete out of the game and on others i have had to reset/put my computer in then out of sleep mode to get out of it.

I've read on some of the other posts that copying my save files then deleting the file at C:\Program Files\Steam\SteamApps\[username]\sin episodes emergence folder and then copying my save files back might get the game working or If that l doesn't work deleteing my ClientRegistry.blob file from C:\Program Files\Steam might work.

HI
I tried the both the above and the game ran for a good 20 minutes or so but then it did the same thing. The only different thing is that every time now i get the message that i mentioned before about the memory not being able to be read and and i'm able to click on the ok button and the game then closes.

sounds like ur system is overheating, try getting some better cooling when u use havey loads it generates heat causeing ur compoents to get hot, witch will cause ur memorey to get too hot then will crash out, explains why ur only geting a 20 min of play. lets just say i've had more technical problems then most people.

Neaver had overheating problems before. Can play every other game i own including oblivion (which is one of the most hardware intensive games you can get) for hours and my computer neaver crashes with them. Plus it's not the actual computer crashing as i can click on the ok button to the above mentioned error message and i'm returned to Windows which is running fine, this again points to a problem with the game itself!
Thanks anyway, anyone else got any ideas.

I ran the steam support program and realized my video drivers were out of date because I forgot that I had to system restore to fix my sound. But I fixed that and ran it again and everything passed except for this:
* Services: Failed

The following services were found on your system. Please try disabling the service or uninstalling the application assoicated with them, and see if that resolves your issue
o Service: Ati HotKey Poller
Ati HotKey Poller has been reported to cause mouse and keyboard lag.
Severity: Low

I did disable the service, but I can't figure out how to uninstall it. After fixing all these problems I can run the game for awhile but still get booted with the same "memory could not be read" etc. error message seemingly at random. Sometimes I get a good 20 minutes of game time, sometimes a lot less and sometimes it crashes right when I load up a game. I also tried each and every tech support suggestion listed on the steam support program, none of which seemed to help. Please help.

Most of the people who are seeing this issue have corrupt GCF files whether steam says they do or not. The most drastic way to fix this issue is to delete the .gcf's that have been downloaded for sin and re-download them through steam. If you bought the game retail, this is a fairly harmless procedure, but if you bought from steam, you unfortunately have a rather hefty download. We are currently investigating other possible solutions to this issue, but as of now re-downloading your gcf's is the supported fix.

Please make sure you close steam entirely and then delete:
The ClientRegistry.blob file in your steam folder
All SiN Episodes GCF files in your steamapps folder

Just to update everyone...
Between crashes i managed to progress through the game a little and once i got past the part of the docks where all the trains are and into the laboratory sections the crashing stopped and i was able to play for as long as i wanted. Seems to me as though there may be some problematic code or something in the docks section.
